+## Unregister Tags/Filters
+
+In some cases it's desirable to disable some tags/filters (see [#324](https://github.com/harttle/liquidjs/issues/324)), you'll need to register a dummy tag/filter in which an corresponding Error throws.
+
+```javascript
+// disable a tag
+const disabledTag = {
+    parse: function(token) {
+        throw new Error(`tag "${token.name}" disabled`);
+    }
+}
+engine.registerTag('include', disabledTag);
+
+// disable a filter
+function disabledFilter(name) {
+    return function () {
+        throw new Error(`filter "${name}" disabled`);
+    }
+}
+engine.registerFilter('plus', disabledFilter('plus'));
+```

+## 反注册标签/过滤器
+
+有时可能需要禁用一些标签/过滤器（比如 [#324](https://github.com/harttle/liquidjs/issues/324)），注册一个假的标签/过滤器并在里面抛出相应的错误即可。
+
+```javascript
+// 禁用标签
+const disabledTag = {
+    parse: function(token) {
+        throw new Error(`tag "${token.name}" disabled`);
+    }
+}
+engine.registerTag('include', disabledTag);
+
+// 禁用过滤器
+function disabledFilter(name) {
+    return function () {
+        throw new Error(`filter "${name}" disabled`);
+    }
+}
+engine.registerFilter('plus', disabledFilter('plus'));
+```
